'Adams, Norwalk, Conn., and Henry L. Kirby, Upper Darby, and George L-Steinbronn, Philadelphia, Pa., assignors to John B. Stetson Company, Philadelphia, Pa., a corporation of Pennsylvania Application July 5,1956, Serial No. 595,992 14 Claims. 01. 2s s This invention relates to a felting machine for shrinking and felting hat bodies and the like.
After the fur. to form a felt hat has been blown upon the forming cone it may be dipped into scalding water and then given a'preliminary manipulation or otherwise treated to harden it suflicieritly for safe handling. The hats in this early form of manufacture are referred to as bats and'the blowing and shrinking of the bats are carried on in the back ,shop.. Although certain machines and processes have been developed to carry on the shrinking with the bats folded flat, the more generally used machines and processes include first the placing of several of the bats superimposed in a cloth such as flannel, burlap, or other material and rolling them by hand into a roll or bundle and in some plants these bundles, while saturated, have been rolled and worked by hand and in others, machinery'has been used to shrink the bats. The bundles are then unrolled and the bats rearranged in them and again rolled up, and a further treatment given to them. This process is repeated 21 number of times until the bats attain the desired size for further treatment. 1
7 One series of machines for carrying on these operations was developed by H. A. Genest and a patent i1- lustrating one of his machines is No. 1,738,494, December 3, 1929. This patent illustrates a machine for carry ing on the felting or shrinking operation with the bundle of bats being under pressure of two upper rolls, as the bundle rolls upon two lower rolls. A stream of water is played upon one of the rolls for absorption by the bundle of bats. This machine is designed to roll the bats for a given period of time and then to automatically stop so that the bundle may be removed from the machine and another one inserted after which the machine is started again and a new bundle of bats given a further shrinking operation for the period of time for which the machine is designed. I
Another early machine which was used to perform the initial felting or shrinking operation is illustrated in the patent to Eickemeyer No. 289,243, November 27, 1883. In the construction of the machine of this patent, the machine was intended to operate continuously and the degree of pressure was determined by hand. The hat was automatically discharged from the machine by depressing a foot lever which raised one of the supporting rolls.
The objects of the instant invention are to render the felting or shrinking operation of the bundle of bats more automatic, to relieve the operator of the continued necessity of manipulating the machine and to make it possible to vary the time of shrinking operations for which the machine may be set.
Another object of the invention is to provide a machine which may rotate continuously and thus avoid the starting and stopping which is injurious to the machine as well .as consuming the attention of the operator. In the use of the machine a number of bundles of bats are in 2,892,242 Patented June 30, 1959 process continuously so that when one bundle of bats is ejected from the machine, another is immediately ready to be placed in the machine.
Another object of the invention is to eject the bundle of bats from the machine at the end of the time fixed for the shrinking of the bats in the bundle.
Another object of the invention is to utilize the direction of-rotation of the bundle working and supporting rolls to aid in the ejection of the bundle of bats from the machine.
Another object of the invention is to so place the ejecting means that they will not interfere with the operation of the rolls on the bundle of bats.
Other objects and advantages of the machine will be apparent from the following description and the accompanying drawings forming a part hereof and in which:
Figure 1 is a front elevational view of the complete machine with the central forward housing broken away.
Figure 2 is a front elevational view of the complete machine with the operators work bench standing in front of the machine.
Figure 3 is a left end elevational view of the machine with the operators bench in place.
Figure 4 is an elevational view of the left side of the top of the machine with the casing door open.
Figure 5 is an end elevational view on the right side with the upper casing door open.
Figure 6 is a transverse sectional view through the upper portion of the machine, looking from the right.

Figure 8 is a fragmentary sectional view showing the attachment of the slats to the roll.
Figure 9 is a diagrammatic view of the elements of the machine with their electrical operating mechanisms.
Figure 10 is a fragmentary view showing the light beam broken by a bundle.
In the drawings similar numerals refer to similar parts throughout the several views.
The machine 1 stands upon a base 2 and in the side frames 3 of the machine are supported the large lower bat bundle supporting roll 4, the forward roll 5 and the upper roll 6. mounted on shafts 8 keyed to gears 9 which are rotated in the same direction by chain 10 on the right side of the machine. The webs 7 each have notches 11 out into their perimeter into which the ends of slats 12 snugly fit and the slats are held in place by the bands 13 and screws 14 passing through the bands, the slat ends and into the webs. On the left side of the machine the large lower roll shaft 8 has thereon a gear 15 driven by motor 16 by means of chain 17.
The bundle of bats 18 is dropped or thrown between the two rolls 4 and 6 until the bundle rests on roll 4. All the rolls rotate in the same direction as shown in Figures 6 and 9, counter-clockwise, so that the direction of rotation of the bearing side of forward roll 5 is forward, toward the front of the machine. Hot water is directed through orifices in a horizontal section 19 of pipe 20 toward the rolls in the form of a spray and the portion of this water not absorbed by the bundle of bats falls to tray 21 at the bottom of the top section of the machine. The slats constituting the face of rolls 4 and 6 are cut out as at 22 spaced from the ends of the rolls. An angular ejector 23 with a long curved upper section 24 and a lower section angular thereto 24 is recessed into these openings in rolls 4 and 6, to'engage the bundle of bats upon being forced forwardly. When forced forwardly they elevate the bundle to the top of roll 5, which, rotating forwardly, drops the roll out of the machine. The
A radiation-responsive device such as a photo-cell 31 is on the left side of the machine and a light 32 is on the right side of the machine. These elements are so placed as to pass a beam of light diagonally across the space occupied by the bundle of bats when in bat rolling and felting position between the rolls, as illustrated in Figures 6 and 9.
A work bench 33 extends forwardly of the machine as illustrated in Figures 2 and 3 on which the rolls of bats may be rolled up and unrolled as the bats are changed to their different positions within the bundle or roll to efiect their proper felting or shrinkage. The operator stands at the left of the machine and faces the work bench to perform this service, then places the bundles of bats in the machine for the rolling and shrinking operation. The Work bench has water receptacles 34 at each side connected as at 35, and a water inlet 36 to cool the operators hands. This bench also has a sloping top, sloping away from the operator With a drain 37 leading into the tray 21 as shown in Figure 1 from which there is a drain 38 leading from the whole machine.
The photo-cell is connected to a timer 39 which is actuated upon the breaking of the beam by the presence of the bundle in the machine and a selected time after the breaking of that beam the timer closes a circuit, actuates the solenoid 30, which throws the ejector arms out or forward and ejects the bundle of bats from the machine.
When starting the machine in the morning, the starting button 40 may be pressed and the machine may then continue throughout the day in its operation until stopped by pressing the stop button 41. Should the motor be stopped because of overheating, it could be started again by pressing the reset motor button 42.
For any given run of bats the timer 39 may be set to leave each bundle of bats between the rolls for a fixed length of time and then all that the operator needs to do is to insert the bundle of bats the number of times required after each changed position of the bats in the bundle until each bundle has the required number of treatments in the machine, and while one bundle is in the machine for shrinking, others may be prepared so that the machine is kept working continuously. As the machine is automatically controlled for the length of time each bundle remains in it, uniformity of felting is obtained since the moisture also is uniformly applied at a uniform temperature. Also the pressure and speed of the rolls is uniform so that the hats produced on the instant machine are far superior to those produced on machines leaving these variables to the determination of the operator, or those worked by hand, and the operator himself is saved considerable work in stopping and starting the machine for each operation on a bundle and the working life of the machine is greatly increased because of its continuous operation. The vapors are taken off by suction placed on hood 43. All moisture is retained in the rolling section of the machine and kept [from the operating elements by the casing and the tray 21.
